GL: 3-D Graphics

Scott Owens

The sgl libraries provide access to the rendering
functions of OpenGL 1.5 and GLU 1.3
libraries. The sgl libraries to not address
system-level concerns, such as the attachment of GL rendering contexts
to displays. Instead, the libraries should work with any Racket
extension that provides GL with access to the system (such as a
binding for glx). Notably, the racket/gui/base
library provides support for rendering contexts via the
canvas% class and its with-gl-context
method.
